I perhaps can support added dialogs to IDLE to manage packages (having
it shell out to pip, if no api is forthcoming), but I don't think I can
support having the repl inside of IDLE intercept pip's command line
syntax and do anything OTHER than giving a better error message.

Maybe it could prompt the user that the interpreter will need to be
restarted for the changes to take effect. IDLE runs the interactive
interpreter in a separate process so it could restart the subprocess
without closing the GUI (after prompting the user with a
restart/continue dialogue).
I'm not sure if the standard interpreter would be able to relaunch
itself but it could at least exit and tell the user to restart (after
a yes/no question in the terminal). The command could also be limited
to the when the interpreter is in interactive mode.
How it works in the terminal is less important to me than how it works
in IDLE though; being able to teach how to use Python through IDLE
(deferring discussion of terminals etc) is useful for introductory
programming classes.
